After a week or two testing on the bench I've now installed the TX unit outside with the RX feeding my existing Cumulus software.
I've had a Fine Offset (Maplin badged) station up and running since 30 December 2008 and had hoped to have the WeatherDuino running at the same time so I could compare the results. Unfortunately though the FO outside transmitter failed completely around mid-October so I've not been able to do any comparison.
As a temporary setup, partly for testing and partly so I can get data flowing again, I've removed the FO pcb from the outside housing and replaced it with the SHT21 sensor for the WeatherDuino. That is housed in a small weatherproof box attached to the mounting pole with about 75cm of cat5 cable connecting the sensor.
Everything seems to be working well so far. I think having the trimmer pot on the TX board has really helped to improve the output from the FO wind direction sensor - the Cumulus graph seems a lot "cleaner" than it was before.
For anyone who wants to have a look, go to:

I wanted to watch carefully the battery voltage as I need to swap rechargeable batteries at present. I discovered some other interesting web tags in Cumulus so tried experimenting with them - see the "hardware" link at the bottom of the page. Battery condition & voltage is there and work great. A couple of other Davis specific statistics are available but I don't know what, if anything, they refer to in the WeatherDuino. The "RX Firmware" shows 1.90, there is also a reading for data packets although it never goes higher than 9. Hopefully will have more time to experiment and explore soon.
Of course thanks must go to Werk_AG for making this whole project available in the first place and for the tremendous work he does in maintaining and improving it as well as supporting those of us building it.
